June 2026 (getlago/lago-api) focused on performance, data integrity, and API reliability around wallet management and billing entity handling. Delivered asynchronous wallet update processing and webhook alignment to drastically reduce user-facing latency; ensured atomic operations by enqueuing wallet refresh after commit; introduced awaiting_wallet_refresh flag. Fixed critical billing-entity propagation issues when moving wallets between entities and exposed billing_entity_code in wallet transactions with preloaded associations to prevent N+ queries. Introduced grants_target_top_up for wallet recurring transactions to allow target rules to grant credits, enabling more flexible promotions and revenue-neutral scenarios. These changes improve system throughput, accuracy of wallet balances during API flows, and visibility of billing context in wallet transactions.

May 2026: Delivered end-to-end multi-entity billing capabilities, strengthened data accuracy across wallets and analytics, and improved operational hygiene. The team shipped API/GraphQL surface enhancements to bind subscriptions to billing entities, exposed billing_entity_id for better visibility, and expanded analytics to report by entity. Frontend and data layers now present per-entity revenue and credit-note insights, while pagination and currency-aware balance calculations reduce data drift and improve reliability.

April 2026 — Lago API delivered multi-currency billing across subscriptions, wallets, and invoices by deriving invoice currency from the plan's amount_currency and using organization_default_currency as a safe fallback. Replaced hardcoded currency paths with dynamic resolution and added clean accessors. Also fixed data pipeline reliability by touching Invoice on InvoiceMetadata changes so updated_at bumps trigger re-sync via Prequel. Overall impact: enables international customers to bill in multiple currencies with accurate invoices, reducing manual intervention and improving revenue integrity. Technologies demonstrated: Ruby on Rails, ActiveRecord associations, RSpec tests, payment-provider integrations (Adyen, Moneyhash, Stripe), and data pipeline orchestration.
